Don't think it is possible.

Hi all,
We have a 5 yr. old Nissan Tiida, running like a dream.
107000K's. 1 set of Tyres, 1 Battery, that's it.
I like to do the Miles Per Gallon on the car, rather than the Litres per 100K's. just can't get my old head around it.

So I put in the K's & multiply by 4.54609 & divide by Fuel.
Sounds right ???.
This car, then is supposed to be doing 62.39 MPG. Not in a blue fit.
The other way is to put in K's, multiply by 2.84 & divide by Fuel, = 38 MPG, a lot more like it, but I suspect that is still wrong.
Does anybody do this like I like too.

km's need to be converted to miles so DIVIDE by 1.61
L's need to be converted to Gallons so DIVIDE by 4.55

Then divide the Miles by the Gallons.

OR

km/L * 0.137 will get you to Miles per gallon

We did a run across to SA last year in SWMBO's Tiida. About 1200km's each way, used the cruise control to sit on 100kph all the way, very nice feature. Did a comparison there and back too, premium there, regular back. To make the use of premium worthwhile, I was hoping for 10% better consumption to balance the extra cost. The result though, standard won on consumption by about 5%.
Not exactly a scientific study, but food for thought.

There are a few calculators on the net available. I plugged in "fuel consumption conversion" and got a whole page of them. This one might suit you,but there are many others.

Online Conversion - Fuel Consumption Conversion

To go from L/Km to MPG just multiply by 2.84. MPG means something to me too, while L/100Km is a bit like swearing in a foreign language .

Issatree has his answer so I can hijack the thread.

I grew up as we were changing to metric and can mostly work in both worlds if forced - so I don't find it an issue. But it is a lot easier to estimate fuel stops for a trip using L/100k. Especially as we buy fuel in litres and most odometers (by now) are in kms. Try it using just a map or roadsign and no pencil and paper/calculator.
